I run version v1.17 (1d8b790) and for the past 6 months or so everything has been running smoothly, except for the occasional Token expiration that I had to manually refresh.
As of this morning both my tenants stopped fetching emails from the configured mailbox. So I went to check on the Admin board and to my surprise, the tokens were up to date. The Azure secret keys are still in their validity period, too.
When trying to save changes, I got an "AUTHENTICATE failed" error.
I tried to reconnect once and Auth0 + Microsoft seem to be ok :
After that the token even refreshes
These are the permissions on azure application :
But OSTicket refuses the authentication :
Nothing has changed on our configuration neither Azure side or OSTicket side
